Publication number: 20120026588Abstract: A tunable spectral filtration device is disclosed that includes one or more pairs of interference filters in series, wherein each element of each pair is independently selected from one or more options, independently positioned to intersect a path of converging or diverging light, and independently tilted with respect to the light path. Each filter may be either of a bandpass type, a shortpass type, a longpass type, a notch type, or multiple combinations thereof. Each filter in the series may be independently selected and tilted to tune the net spectral output of the series. The elements in a pair of filters may be tilted in opposite directions so as to cancel angle-of incidence dependent broadening of the spectral output of the individual filters for noncollimated light, as well as cancel translational shift of the transmitted light rays.Type: ApplicationFiled: July 22, 2011Publication date: February 2, 2012Inventors: Gilbert Feke, Douglas L.

Publication number: 20100220836Abstract: An imaging system and method for imaging an immobilized object. The imaging system includes a support member adapted to receive the object in an immobilized state. The system also includes first means for imaging the immobilized object in a first imaging mode to capture a first image, and second means for imaging the immobilized object in a second imaging mode to capture a second image. The first imaging mode is selected from the group: x-ray mode and radio isotopic mode. The second imaging mode is selected from the group: bright-field mode and dark-field mode. The first and second means for imaging may be included in a capture system having a camera, a first mirror on a first side of the support member for reflecting light to capture the first and second images and a second mirror on a second, opposite side of the support member for reflecting light to capture a third image from an opposite side of the object.Type: ApplicationFiled: April 20, 2010Publication date: September 2, 2010Inventors: Gilbert D.

Publication number: 20100218140Abstract: A method for forming a sequence of images of a subject obtains at least first and second image sets of the subject, each image set having a given angular displacement relative to an axis of rotation of the subject, each image set having at least a first component image of a first diagnostic modality at the given angular displacement and a second component image that is co-registered to the first component image at the given angular displacement. The first image set is selected as the selected image set for display. A synthesized image is formed by combining image data for the at least first and second component images of the selected image set and the synthesized image is displayed.Type: ApplicationFiled: March 3, 2010Publication date: August 26, 2010Inventors: Gilbert D.

Publication number: 20100208348Abstract: A tunable spectral filtration device comprises at least one optical filter for intersecting a first path of converging or diverging light comprising an axis at a first angle of incidence and at least one device positioned to enable a second path of the converging or diverging light to pass through the at least one optical filter at a second angle of incidence. The optical filter comprises at least one coating and is tiltable over a plurality of angles with respect to the axis. The first angle of incidence is opposite in sign to the second angle of incidence, such that the positioning of the at least one optical filter and the at least one device substantially cancels angle-of-incidence dependent spectral broadening and/or polarization dependent spectral broadening of the converging or diverging light.Type: ApplicationFiled: February 19, 2010Publication date: August 19, 2010Applicant: CARESTREAM HEALTH, INC.Inventors: Gilbert D.

Patent number: 7734325Abstract: An imaging system for imaging an object. The imaging system includes a support member adapted to receive the object in an immobilized state. The system also includes first means for imaging the immobilized object in a first imaging mode to capture a first image, and second means for imaging the immobilized object in a second imaging mode, different from the first imaging mode, to capture a second image. The first imaging mode is selected from the group: x-ray mode and radio isotopic mode. The second imaging mode is selected from the group: bright-field mode and dark-field mode. A removable phosphor screen is employed when the first image is captured and not employed when the second image is captured. The phosphor screen is adapted to transduce ionizing radiation to visible light. The phosphor screen is adapted to be removable without moving the immobilized object. The system can further include means for generating a third image comprised of the first and second image.Type: GrantFiled: September 8, 2005Date of Patent: June 8, 2010Assignee: Carestream Health, Inc.Inventors: Douglas L.

Patent number: 7706501Abstract: A method and apparatus are disclosed for measuring long bone density of small animals. A phosphor screen or plate is provided of a type that transduces incident ionizing radiation to emitted light. A small animal is positioned before the phosphor screen or plate and exposed to soft X-radiation having an energy level in the range of 11 to 16 Kev. Light emitted by the phosphor screen or plate is captured using a digital camera and a digital X-ray image is prepared of a long bone of the animal. The X-ray image is transformed into an X-ray density image and a region of interest is defined on the long bone in the X-ray density image. At least one row of pixels is scanned within the region of interest of the X-ray density image. A nonlinear least squares analysis of data obtained from the scanning step is conducted using a cylindrical model for the long bone within the region of interest.Type: GrantFiled: September 4, 2008Date of Patent: April 27, 2010Assignee: Carestream Health, Inc.Inventors: Douglas L.
